Debian和Ubuntu国内安装docker和dockercompose

01 - 安装docker

0、如果你过去安装过 docker，先删掉

sudo apt-get remove docker docker-engine docker.io containerd runc
sudo apt-get purge docker-ce docker-ce-cli containerd.io
sudo rm -rf /var/lib/docker
sudo rm -rf /etc/docker
sudo rm -rf /var/run/docker.sock
sudo rm -rf /var/run/docker.pid

1、更新软件源列表

sudo apt update

2.安装软件包依赖

ssudo apt install -y apt-transport-https ca-certificates curl gnupg2 software-properties-common

3.在系统中添加Docker的官方密钥

Debian

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

Ubuntu

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

4.添加软件仓库

Debian

echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/debian \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Ubuntu

echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

5.开始安装Docker（ce表示社区版）

sudo apt update
sudo apt install -y docker-ce

6.查看安装的Docker版本

docker -v

7.启动Docker服务

sudo systemctl start docker

8.设置开机自启动docker

sudo systemctl enable docker

9.查看Docker是否开启，出现绿色圆点表示服务正常开启

sudo systemctl status docker

02 - Docker 镜像源配置

1、修改配置文件

nano /etc/docker/daemon.json

2、按照以下信息配置

{
    "registry-mirrors" : [
    "https://registry.docker-cn.com",
    "http://hub-mirror.c.163.com",
    "https://docker.mirrors.ustc.edu.cn",
    "https://cr.console.aliyun.com",
    "https://mirror.ccs.tencentyun.com"
  ]
}

3、重启 Docker 服务

sudo systemctl daemon-reload
sudo systemctl restart docker

03 - 安装Docker-compose

curl -SL https://github.com/docker/compose/releases/download/v2.18.1/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

下一步不是必须的

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

验证是否成功

docker-compose --version
